ROD AND CABLE COUPLING.

SPECIFICATION formingpart of Letters Patent No. 626,527, dated June 6,1899.

A licatio filed December 14,1898. Serial No. 6 99,235. (No model.)

To all whom, it may concern:

Be it known that I, IVILLIAM OONNELLY, a citizen of the UnitedStates,residing at Toledo, in the county of Lucas and State'of Ohio,have invented certain new and useful Improvements in Rod and CableCouplings; and I do hereby declare the following to be afull, clear, andexact description of the invention, such as will enable others skilledin the art to which itappertains to make and use the same.

. This invention relates to rod and cable couplings; and it consists incertain improvements in the construction thereof, as will be hereinaftermore fully described, and pointed out in the claims.

My invention is illustrated by a coupling which is particularly adaptedfor connecting surface rods or cables used in pumping oilwells, asfollows:

Figure 1 shows an elevation, the-point of view being from the right ofFig. 2. Fig. 2 showsan elevation, the point of view being from the leftof Fig. 1. Fig. 3 shows an end elevation of the device, the point ofview be ing from the bottom of Figs. 1 and 2.

O marks the coupling, which comprises a piece of metal having thelongitudinal opening 0' (see dotted lines) for the introduction of therods. The coupling is provided with the ear 0 through which are passedthe bolts 0, on which are screwed the nuts 0 A slot 0 extendslongitudinally through one side of the coupling into the opening 0 Themetal is preferably connected at the center 0. In practice the rod A isinserted in the opening 0 and the nuts 0 screwed down with sufficientforce to spring the metal coupling, so as to securely clamp the rod. Theclamping effect by this means is limited to the frictional resistance ofthe walls almost entirely. It is preferable,therefore,to supplement theclamp formed by the bolt 0 by the set-screws G ening their engagement.

The coupling may be used for coupling two.

rods, as A, or two cables, as B, or rods and cables, as shown. A ring 0is provided in the back of the coupling for attaching the supportingmeans where-the coupling is used 011 surface rods. At one end of thecoupling there is a supplemental clamp 0, having the opening 0 (Seedotted lines therein.) A wall of metal 0 separates the openings 0 and 0A clamping-bolt 0 having the nut c, is passed through an ear 0 in thesupplemental clamp 0 A set-screw O is arranged opposite to one of theset-screws O and is used in alike manner to the set-screw O By passingthe set-screw O and bolt C in opposite directions from that of theset-screw O and bolt 0' the set-screws C and nut 0 can more readily beengaged by a wrench.

Where the device is used for a coupling simply for surface-rods, theauxiliary clamping portions 0 may be omitted or need not be used ifpresent. It is useful in forming a loop with which to secure the end ofa line of rods or cables.

The coupling asawholeis preferably formed of an integral casting.

What I claim as new is- 1. In a rodcoupling, the combination of thecoupling portion, 0, formed of an integral piece of metal having theopening, 0 and slot, 0, in one side only thereof; and the clampingbolt,O, therethrough out of the line of the opening 0 2. In a rod-coupling,the combination of the coupling portion, O, having the opening, a", andslot, 0, therein; the bolt, O, therethrough the auxiliary clampingportion, O thereon; and the bolt, 0, therethrough substantially asdescribed.

3. In a rod-coupling, the combination of the coupling portion, O, havingthe opening, 0 and slot, 0, therein; the bolt, O, therethrough; theset-screw arranged to engage a rod in the opening, 0 the auxiliaryclamping portion, 0 and the bolt, 0 therethrough.

4. In a rod-coupling, the combination of the coupling portion, 0, havingthe opening, 0 and slot, 0, therein; the bolt, 0, therethrough; theset-screw arranged to engage a rod in the opening, 0 the auxiliaryclamping portion, 0 the bolt, 0, therethrough; and the setscrew, Oarranged to engage the rod in the opening, 0

5. In a rod-coupling, the combination of the coupling portion, 0, havingthe opening, 0

and slot, 0, therein; the bolt, 0, therethrough;

the set-screw arranged to engage a rod in the opening, 0 the auxiliaryclamping portion, C the bolt, C therethrough; and the setscrew, 0arranged to engage the rod in the opening, 0 said set-screws, C and Cbeing arranged on opposite sides of the coupling portion 0, for thepurposes described.

6. In a rod-coupling the combination of the coupling portion, 0, havingthe opening, 0 slots, 0 c, with the bridge-piece,c,between said slots,and having the ears, c thereon; bolts, 0 0, arranged through said ears;set-screws C 0 arranged to engage the rods in the openarranged on theopposite side of said coup-' ling from that of the set-screw, 0

In testimony whereof I aflix my signature in presence of two witnesses.

WILLIAM OONNELLY.
